Source: Best Bug ever, two companions
Another individual stated the same thing happened to them:
This was stated to be fixed in the last patch but this was posted today.Something similar happened to me once not that long ago. When I tried to change companion I got both at the same time. No idea how or why this happened, as I didn't do anything unusual and it never happened again.
It's too late for me to play around with tonight but I wonder if this is latency related or maybe a double-registered summon button click.
Ideas?
Update/Edit:
It appears the cat's almost out of the bag: Double-companion
I know i've seen it before where the companion no longer appears at the top right but after 1 hour of gameplay, i can't get it to happen again. What makes this happen, would be the next best question.Log in. Jump on mount and run somewhere. Jump off mount - companion is next to me. Do a bit of fighting then notice that the companion avatar isn't at top of screen.
Unsummon companion and resummon. Avatar appears - but now I have two companions. Can select and heal both. Both attack targets.
Unsummon, ride mount, dismount, resummon. One companion.
